SIGNAL LAMP.

Application filed November 20, 1928. Serial No. 675,901.

To all whom it 'IIldIl/OOILCGWl-f Be it known that I, MARTIN M.CUNNINe-- HAM', a citizen of the United States, and a resident of FarRockaway, borough of- .signaling lamp's which are especially designedfor use by.tra fiic oflicers or drlvers of vehicles.

The broad object of the present invention is to provide a handsignalingla-mp which is adapted to be associated with the Wrist and handof the user whereby the same may i be conveniently emploiyied for thepurpose of giving signals in tra More specifically the inventioncontemplates a hand signaling lamp provided with a switch forcontrolling the energizing of the lamp, which switch is automaticallyoperable upon movement of the hand or arm to si aling position forclosing the circuit to said lamp.

The invention furthermore contemplates a palm lamp, the casing of whichis so'constructed as to snugly fit the wrist and contour of the palm ofthe hand in order that the interference of the same with the use of thehand is reduced to an absolute minimum..

'As a still further object the invention contemplates a hand signalinglamp of the character set forth which is comparatively simple in itsconstruction, inexpensive to manufacture and produce and wh1ch isthoroughly reliable and highly eflicient in its purpose. 7

With the above recited and other objects in view, the invention residesin the novel construction set forth in the following speci fication,articularly pointed out in the appended c aim and lllustrated in theaccompanying drawings, it being understood that the right is reserved toembodiments other than those actually illustrated herein to the fullextent indicated by the general meaning of the terms in which the claimis ex- Fig. 2' is a side view with parts in section illustrating theconnection between the conduit-wires and the batter Fi 3 is a sectionalview taken approximate y on the line 3--3 of Fig. 2.

Fig. 4 is a sectional view taken approximately on the line 4-4 of Fig.2.

Fi 5 is a face view of a modified form of signa lamp in applied positionon the back of the hand.

Fig. 6 is a side view thereof.

Referring to the drawings by characters of reference and rticularly totheconstruction illustrate in Figs. 1 to 4 inclusive, the hand signalingpalm lamp is illustrated which consists of a housing or casing 10 theexternal surface of the rear wall 11 of which is shaped to closelyconform to and fit the wrist and palm of the hand. The upper terminal 12of the casing drical formation and is provlded with a transparent panel13 constituting the front wall to allow the rays from the lamp bulb 14to be visualized therethrough. The lamp bulb is supported in a suitablesocket 15' in the terminal 12 and is connected by circuit wires 16 and17 to the spaced contacts 18 and 19 carried by an insulating strip 20 isof cylintion on the wrist and hand. .A s iding circuit closing element24: is inounted in the terminal 21 and is provided with a reduced boss.25 which protrudes throu h a guide slot 26 in the coverlng plate 27. Te circuit closing element 24 is provided with contact members 28 and 29which are connected with terminal posts 30 and 31 projecting upwardlythrough the boss 25. A spring 36 normally functions to move the circuitclosing element 24 to a position to dispose the contact members 28 and29 out of engagement with the contacts 18 and 19. The terminal posts 30and 31 are connected to the terminals of the conduit wires 37 which areinsulated and inte'rtwisted and lead to the pole terminals 38 and 39 ofa pocket battery 40. A coiled contractile spring 41 is secured and theirconnection with the pole terminals 38 and 39. Normally when the arm A ofthe .user is in a non-signalin position a sufiicient slack is producedin the ength of the circuit wires 37 to allow the spring 36 to functionto shift the circuit closing element 24 to a position inwhich thecontact members 28 suflicient pull is exerted on the circuit wires 37 tomove the circuit closing element 24 against the actionvof the spring 36whereby the contact members 28 and 29 engage the contacts 18 and 19 forclosing the circuit and energizing the lamp bulb 14. By shaping the rearwall 11 of the casing-or housing 10 to conform to the wrist and palm ofthe hand, it will be noted that the device is comfortably mounted in aconvenient position for signaling purposes and reduces the interferenceof the same with the use of the hand, to an absolute minimum.

In the modified adaptation of the invention illustrated in Figs. 5 and 6the construction is identical with that of the preferred embodiment withthe exception that the casing 10 and the rear wall 11' thereof are on astraight line for fitting the same to the wrist and back of the handwhereby the de- 80 of peripheral side transparent paneled open- 86.

ings 12 which may also be pro vided in the terminal 12 of the first formand which panels are designed for the purpose of allowing for thepassage of the light rays from the lamp when illuminated whereby thehand '03 of the user will be flooded with light. I claim v A palm lampfor iving hand signals comprising an elongate housing, the said housingbeing shaped to fit the contour of the 45 wrist and the palm of thchand, a switch in'the-housing, the said switch located in that end ofthe housing which fits the wrist, a'windowed compartment in that end ofthe housing which fits the palm, a lamp in the said windowedcompartment, and means for fastening the housing to the wrist.
